14 to 15 asycnClick

Http.sys creates 16 threads / core by default. Very likely that you need more threads to handle that number of users with 8 cores. You could try 32 or even 64 and see how it behaves.
Also, how is performance compared to previous version built with IW 14?

In case you want to change the number of threads / core, just use this:

In your DPR file, add unit to the uses clause:

IWHSysServer

Then add this line:

begin
  TIWHttpSysServer.DefaultThreadsPerCore := 32;    // <- Set the number of threads per core here (the default is 16)
  TIWStartHSys.Execute(True);
end.

Thanks. I will try this and let you know the status.
it is faster than the previous version IW14.
